Using CRON Expression in Salesforce

Hello to all the salesforce developers, here in this blog I am covering a very crucial topic that we all use in our coding skills - CRON expression. As we all know that Salesforce provides us with a very great feature of Scheduling an apex class. In a standard way through customization part, we can schedule an apex class with the frequency of weekly days or monthly dates with a preferred start time. But through CRON expression we can schedule an apex with our customized date time or occurrence through code. That’s an interesting feature that salesforce allows developers to customize according to their own need and scenario.

What is CRON?

CRON is a software utility that is a time-based job scheduler in Unix-like computer operating systems. Developers who want to set up and maintain software environments, use this CRON to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals.
